In May the Blenheim District Court heard that two employees were servicing an engine at Woodbourne Airfield.
A spokeswoman for what was then known as the Ministry of Labour, Jean Martin, said the engine being serviced was mounted on a testing site and accessible from an elevated work platform.
With one employee at the computer in the control room, Miles Hunter, 51 went outside to check the engine. To access the right hand side he had to walk in front of the engine, past the air intake.
"When the employee maneuvered in front of the engine he wasn't holding onto the handrail around the edge of the platform and was pulled into the engine," Ms Martin said.
Mr Hunter joined Safe Air in 2005 and had been around machines and engines his whole working life.
He had previously been a motorcycle mechanic and put himself through the Nelson Marlborough Institute of Technology to prepare for a career with the company.
At the time of the incident an Air NZ spokeswoman said the Rolls Royce C-130 Hercules turboprop engine was being tested without its propellers on a remote stand.
A turboprop engine is a combination of a jet engine with a propeller on the front, she said.
